Layout, conforto e satisfação dos usuários em escritórios: uma avaliação pós-ocupação no edifício da sede administrativa do INPE-CRN

This research aimed to identify the link between the layout of workspaces in offices and the design strategies for environmental comfort. Strategies surveyed were focused on the thermal, visual and luminic comfort. In this research, visual comfort is related to issues of visual integration within and between the interior and exterior of the building. This is a case study conducted at the administrative headquarters of Centro Regional Nordeste do Instituto de Pesquisas Espaciais (INPE-CRN), located in Natal/RN. The methodological strategy used was the Post-Occupancy Evaluation, which combined the survey data on the building (layout of workspaces, bioclimatic strategies adopted in the design, use of these strategies) with some techniques aimed at acquiring qualitative information related to users. The workspace layout is primordial to satisfaction and productivity of workers. Issues such as concentration, communication, privacy, personal identity, density and space efficiency, barriers (access, visual and even ventilation and lighting), among others, are associated with the layout. The environmental comfort is one of the essential elements to maintaining life quality in workplace. Moreover, it is an important factor in user`s perception of the space in which he or she are inserted. Both layout and environmental comfort issues should be collected and analyzed in the establishment phase of the programming step. That way, it is possible to get adequate answers to these questions in subsequent project phases. It was found that changes in the program that occurred over time, especially concerning persons (number and characteristics), resulted in changes in layout, generating high density and inflexible environments. It turns difficult to adjust the furniture to the occupants` requirement, including comfort needs. However, the presence of strategies for environmental quality provides comfort to spaces, ensuring that, even in situations not considered optimal, users perceive the environment in a positive way. It was found that the relationship between environmental comfort and layout takes the following forms: in changing the perception of comfort, depending on the layout of the arrangements; adjustments in layout, due to needs for comfort; and the elevation of user satisfaction and environmental quality due to the presence of strategies comfort even in situations of inadequate layout

Parâmetros urbanísticos na regulação do uso e ocupação do solo: estudo da densidade e do coeficiente de aproveitamento nos planos diretores de Natal de 1994 e 2007

A Constituição Federal de 1988 e o Estatuto da Cidade estabelecem o Plano Diretor como instrumento básico da política de ordenamento territorial, tendo como princípio fundamental o cumprimento da função social da propriedade e do direito à cidade. Na perspectiva de adequação às diretrizes e objetivos da política urbana estabelecidos em 1988, o município de Natal elaborou os Planos Diretores de 1994 e 2007, definindo instrumentos e parâmetros de regulação do uso e ocupação do solo possíveis de assegurar o cumprimento da função social da propriedade urbana e de gerar subsídios ao planejamento e à gestão da cidade. Apesar de Natal ter sido um dos municípios brasileiros pioneiros na adoção desses princ pios, antecipando e incorporando os instrumentos que em 2001 viriam a ser definidos no Estatuto da Cidade, identifica-se que alguns desses instrumentos e parâmetros direcionados à regulação do uso e ocupação do solo não tiveram sua aplicação plena, a exemplo do mecanismo de acompanhamento e controle dado pelo Estoque de Área Edificável e da Densidade, que foi substituída pelo Coeficiente de Aproveitamento no Plano Diretor de 2007. Questionando esse procedimento, busca-se na presente pesquisa investigar de que maneira essa substituição do parâmetro densidade pelo coeficiente de aproveitamento influenciou na capacidade da gestão pública de regular os processos de uso e ocupação do solo, de forma a adequar a sua intensificação ao suporte da infraestrutura instalada. Foram tomadas como referência teórico-conceitual as contribuições sobre a prática de planejamento urbano no Brasil, nos marcos do ideário da reforma urbana, com destaque para as reflexõe s de Flávio Villaça, Orlando Alves Santos Junior e Daniel Todtmann Montandon, Luiz César de Q. Ribeiro, Raquel Rolnik, Ermínia Maricato, Laura Machado de Bueno e Renato Cymbalista, José Roberto Bassul e Carlos F. Lago Burnett, e, com relação aos parâmetros de controle urbanístico, o estudo identifica as diferentes abordagens sobre a densidade urbana e o coeficiente de aproveitamento com base nas reflexões de Claudio Acioly Jr., Forbes Davidson, Juan Luis Mascaró, Ricardo Ojima, Marcelo de Souza, José Rámon Navarro Vera e Armando Ortuño Padilla, Nestor Goulart Reis, Marta Dora Grostein e Susana Ricardo Alves. Como conclusão, discute-se a hipótese formulada, inicialmente, de que a mudança de parâmetros verificada colocou limites para o município realizar uma gestão adequada do solo urbano e, portanto, de fazer cumprir a função social da propriedade, considerando a necessidade de adequação entre a intensificação do uso e ocupação do solo e a infraestrutura instalada

O processo de urbanização de Mossorò: dos processos históricos à estrutura urbana atual

The general objective of this academic work is to analyze the relationship between the territorial division and the urban expansion process of Mossoró city, understood here as the production and occupation of space. The urban expansion in Mossoró, since its formation as settlement in 1772 until current days, identifies with the Brazilian urbanization process whose growth is determined by the capitalist development. Thus, the expansion was determined by several economical specializations imposed by the territorial division of work which occurs at an interregional level, and, sometimes at an international level. Then, each specialization determined a moment of the urban expansion of the city, as follows: a) The cattle farmer specialization, between 1772 and 1857, when the urban expansion was shy, is summarized to a commercial square that received goods from Aracati aiming to cover a wide rural area; b) The commercial emporium specialization, between 1857 and 1930, when the urban expansion took an important impulse with the concentration of public and private capitals; c) The salt industry and the agricultural-industrial exporter specialization inside a state of development policy, between 1930 and 1970, when the urban expansion, joined to the settlement of the working class in the urban soil, developed along an important axis -the railway; d) The render of services specialization inside a state of intervention policy, between 1970 and 1990, when the urban expansion was characterized by the accelerated growth rhythm, by the reuse of some spaces, and by space segregation of demanding people; e) The render of services policy inside a neoliberal state policy, since 1990 until current days, when the urban expansion reduced its rhythm abruptly, when only small alterations occurred in the existing spaces. It focused on social policies and on several slums eradication programs. Finally, the territorial structure is deeply articulated with others, no territorial, but economical, social and political, which happens at a national, regional and local rate. Only within a historical and conceptual panorama, it was possible to explain the urban expansion in Mossoró from its formation in 1772 until current days. Therefore, this work is a several discipline analysis of the urbanization process existing in Mossoró

Influência de variáveis arquitetônicas no desempenho energético de hotéis no clima quente e úmido da cidade de Natal/RN

This master thesis aims to assess the influence of the design decisions on the energy building performance of hotels. The research is based on the integration of field study and computer simulation. Firstly, a detailed field study is carried out to identify the characteristics of hotels in Natal, Rio Grande do Norte. The items assessed are occupancies, light and equipment densities, types of air conditioning, total and monthly energy consumption, among others. A second and more comprehensive field study is carried out to identify the range of occurrence of architectural variables, with a larger number of buildings. A base case is modelled in VisualDOE, based on the first field study. Then, a first set of simulations are run to explore the sensitivity of the variables on the energy consumption. The results analyses were the base of a second set of simulations, which combined the most influential variables. The results of 384 models were assessed, and the impacts of design decisions were quantified. The study discusses tendencies and recommendations, as well as the methods advantages and disadvantages

A onda do turismo na cidade do sol: a reconfiguração urbana de Natal

Space reading of Natal City and its reconfiguration from the intensification of tourist activity and the expansion of the services' sector, transiting, primarily, through the geography, the social sciences, the economy, in one main approach that is unaware of science's traditional limitations and recognizes the complexity that involves current world. In face of this agreement it analyzes the social-economic implications that remodel the spaces under the new economic view of services' sector, commanded by the tourism, in an intense process of city's reconfiguration, concentrating in three great axles and their irrigation ways. These changes were about the public-private relation (by the public politics) in the formation of new spaces and in the remodeling of the city's old areas, which, together, had contributed to the tourist activity's appropriation, returning it in a social-economic mosaic that owns obvious reflexes in its space. This fragmentation in the urbane cloth of Natal is expressed by social nature and economic points and, in the scenery, is manifested through the modern forms of city's space occupation by the local elites and services' sector, evidencing their status' district, as well as selecting those areas with bigger capacity to reply to the capital

O Cariri cearense: da ocupação do território à institucionalização da região metropolitana do Cariri

Urbanization in their mearing simpler, the agglomeration of people, occurred from the time that the productive activities have to be based on trade. The first cities arose when the evolution of agriculture allowed the production and storage of surpluses. However, with industrialization was that urbanization becomes intense, according to Singer (1987), the industrial revolution was to stage, from the beginning, the urban area. It requires, in its proximity, the presence of a large number of workers. With respect to the Cariri cearense, the occupation of its territory is associated with the movement of agricultural surpluses produced and reproduced under the hegemony of merchant capital and due to the development of extensive cattle that promoted the territorial occupation of Ceará. From the 1960s, the region has undergone changes in its productive structure due to industrial planning policies of the government of Ceará. However it was in the 1990s that the region itself as economic and urban polo because policies to attract investments from the state government of Ceará. This policy led to boosting trade and services marking the predominance of tertiary activities in the region, especially the retail, wholesale , medical services and education. Investments also consolidated the industrial park area making it diverse, especially the footwear industries, mining, non-metallic minerals, transport equipment, pharmaceutical chemical, food and beverages, rubber and leather and construction. Thus, the aim of this study was to review the region of Cariri cearense occupation of its territory institutionalizing its metropolitan region, to understand what factors influenced the Cariri cearense become an important area in urban and economic terms in the interior of Ceará. In order to develop this research in that refers to the methodological perspective, research is guided by bibliographic studies and also makes use of secondary data analysis (population, GDP, urbanization rate, employment) of the main databases the country, as IBGE, IPEADATA and RAIS - MTE

Avaliação da produção de sedimento na bacia hidrográfica do rio Potengi através do modelo SWAT

Anthropic disturbances in watersheds, such as inappropriate building development, disorderly land occupation and unplanned land use, may strengthen the sediment yield and the inflow into the estuary, leading to siltation, changes in the reach channel conformation, and ecosystem/water quality problems. Faced with such context, this study aims to assess the applicability of SWAT model to estimate, even in a preliminary way, the sediment yield distribution along the Potengi River watershed, as well as its contribution to the estuary. Furthermore, an assessment of its erosion susceptibility was used for comparison. The susceptibility map was developed by overlaying rainfall erosivity, soil erodibility, the slope of the terrain and land cover. In order to overlap these maps, a multi-criteria analysis through AHP method was applied. The SWAT was run using a five year period (1997-2001), considering three different scenarios based on different sorts of human interference: a) agriculture; b) pasture; and c) no interference (background). Results were analyzed in terms of surface runoff, sediment yield and their propagation along each river section, so that it was possible to find that the regions in the extreme west of the watershed and in the downstream portions returned higher values of sediment yield, reaching respectively 2.8 e 5.1 ton/ha.year, whereas central areas, which were less susceptible, returned the lowest values, never more than 0.7 ton/ha.ano. It was also noticed that in the west sub-watersheds, where one can observe the headwaters, sediment yield was naturally forced by high declivity and weak soils. In another hand, results suggest that the eastern part would not contribute to the sediment inflow into the estuary in a significant way, and the larger part of the sediment yield in that place is due to anthropic activities. For the central region, the analysis of sediment propagation indicates deposition predominance in opposition to transport. Thus, it s not expected that isolated rain storms occurring in the upstream river portions would significantly provide the estuary with sediment. Because the model calibration process hasn t been done yet, it becomes essential to emphasize that values presented here as results should not be applied for pratical aims. Even so, this work warns about the risks of a growth in the alteration of natural land cover, mainly in areas closer to the headwaters and in the downstream Potengi River

Estudo de manejo de águas pluviais urbanas na cidade Natal-Rio Grande do Norte

Urban stormwater can be considered as potential water resources as well as problems for the proper functioning of the manifold activities of the city, resulting from inappropriate use and occupation of the soil, usually due to poor planning of the occupation of the development areas, with little care for the environmental aspects of the drainage of surface runoff. As a basic premise, we must seek mechanisms to preserve the natural flow in all stages of development of an urban area, preserving the soil infiltration capacity in the scale of the urban area, comprising the mechanisms of natural drainage, and noting preserving natural areas of dynamic water courses, both in the main channel and in the secondary. They are challenges for a sustainable urban development in a harmonious coexistence of modern developmental, which are consistent with the authoritative economic environmental and social quality. Integrated studies involving the quantity and quality of rainwater are absolutely necessary to achieve understanding and obtaining appropriate technologies, involving both aspects of the drainage problems and aspects of use of water when subjected to an adequate management of surface runoff , for example, the accumulation of these reservoirs in detention with the possibility of use for other purposes. The purpose of this study aims to develop a computer model, adjusted to prevailing conditions of an experimental urban watershed in order to enable the implementation of management practices for water resources, hydrological simulations of quantity and, in a preliminary way, the quality of stormwater that flow to a pond located at the downstream end of the basin. To this end, we used in parallel with the distributed model SWMM data raised the basin with the highest possible resolution to allow the simulation of diffuse loads, heterogeneous characteristics of the basin both in terms of hydrological and hydraulic parameters on the use and occupation soil. The parallel work should improve the degree of understanding of the phenomena simulated in the basin as well as the activity of the calibration models, and this is supported by monitoring data acquired during the duration of the project MAPLU (Urban Stormwater Management) belonging to the network PROSAB (Research Program in Basic Sanitation) in the years 2006 to 2008

Proposta de zoneamento ambiental visando a proteção dos recursos hídricos de uma bacia hidrográfica

One of the most important natural resources for sustaining human life, water, has been losing the basic requirements of quality and quantity sufficient enough to attend the population due to water contamination'problems, often caused by human beings themselves. Because of this, the sources of this resource are often located in remote places of the natural environment to ensure the quality of the water. However, when urban expansion began to occupy these areas, which were once regarded as distant, environmental pollution problems began to occur due to occupation of the land without planning. Based on this occurrence, this study aims to propose environmental zoning for the Maxaranguape river watershed in order to protect its water resources. This is important because this river can serve as a source of supply for the metropolitan area of Natal, the capital of Rio Grande do Norte. In accordance to this proposition, the model of natural soil loss vulnerability (CREPANI et al., 2001), the model of aquifer pollution vulnerability (FOSTER et al., 2006), and the legal incompatibility map (CREPANI et al., 2001) were used to delimit the zones. All this was done with Geographic Information System (GIS) and also created a geographic database update of the basin. The results of the first model mentioned indicated that 63.67% of the basin was classified as moderately stable / vulnerable, 35.66% as moderately vulnerable, and 0.67% as vulnerable. The areas with high vulnerability degree correspond with sand dunes and river channels areas. The second model indicated that 2.84% of the basin has low vulnerability, 70.27%) has median vulnerability, and 26.76% and 0.13% has high vulnerability and extreme vulnerability, respectively. The areas with the highest vulnerability values also refer to part of the sand dunes and river channels besides other areas such as Pureza urban area. The legal incompatibility map indicated that the basin has 85.02 km2 of Permanent Protection Area (PPA) and 14.62% of this area has some incongruity of use. Based on these results it was possible to draw three main zones: Protection and Sustainable Use Zone (PSUZ), Protection and Environmental Restoration Zone (PERZ) and Environmental Control Zone, which are divided into A, B and C. The PSUZ refer to the coastal areas of the basin, where the sand dunes are located. These sites should be areas of environmental protection and of sustainable urban expansion. The ZPRA refer to river channels, which are in high need of rehabilitation. The third zone corresponds to the rest of the basin which should have, in general, the mapping of possible sources of contamination for further control on the use and occupation of the river

Avaliação do crescimento de ocupação da bacia do rio Pitimbu com subsídios para estudos de possíveis impactos sobre os recursos hidricos

The Pitimbu River Watershed (PRW), belonging to Potiguar capital metropolitan area, State of Rio Grande do Norte, contributes, among other purposes, to human using and animal watering. This watershed is extremely important because, besides filling up with freshwater approximately 30% of the south part of Natal (South, East and West Zones), contributes to the river shore ecosystem equilibrium. Face to the current conjuncture, this study aims to evaluate the urban development dynamics in the PRW, applying Cellular Automata as a modeling instrument, and to simulate future urban scenarios, between 2014 and 2033, using the simulation program SLEUTH. In the calibration phase, urban spots for 1 984, 1992, 2004 and 2013 years were used, with resolution from 100 meters. After the simulation, it was found a predominance of organic growth, expanding the BHRP from existing urban centers. The spontaneous growth occurred through the fullest extent of the watershed, however the probability of effective growth should not exceed 21%. It was observed that, there was a 68% increase for the period between 2014 and 2033, corresponding to an expansion area of 1,778 ha. For 2033, the source of Pitimbu River area and the Jiqui Lake surroundings will increase more than 78%. Finally, it was seen an exogenous urban growth tendency in the watershed (outside-in). As a result of this growth, hydraulics resources will become scarcer

Habitação e modernização: Cidade Nova e maneiras de viver em Natal no início do século XX

Analyses the presence of new standards of habitation detected in the construction of the region called Cidade Nova, in the first s years of the XX century. Associates the presence of these new patterns with the historical moment lived by the capital, marked by the urban modernization and by the changes of local life. Map voices that, introduced by the republican groups since 1889, pronounced the overcome of the old city of the XIX century asseverated a new model of town. Make use, as fundamental fonts of research, of the urban chronicles produced by the local intellectuals and the newspapers, like A República. Dialog with chronics that includes since propositions about the colonial past until the preoccupations about the acting of the State on how to order the public space. Identifies on those texts the political motivations and the elements whose where inherent to capitalism that accelerated the changes occurred in the urban space. Demonstrates the gradual occupation of Cidade Nova as an important modification happened in the city from that time on. That neighborhood adopted a new model on how to construct the houses of their citizens and helped to promote the urban life as a whole. From now on, Natal has a space meant for the home of their richest families. Recognizes, from many ways, many discourses, manners of living that was legitimized by the changing of the XIX to the XX century and has his highest point in the 1920´s. And it was representative of the strong attachment about the habits of refinery and order in the essence of the private life of the local urban elites

Evolução da paisagem do baixo curso do rio de Piranhas-Assu (1988-2024): uso de autômatos celulares em modelo dinâmico espacial para simulação de cenários futuros

The lower course of Piranhas-Assu river, located in the north coast of Rio Grande do Norte, Brazil, arouses a keen interest as a study field, once it concentrates, besides petroleum and gas exploration, activities related to shrimp culture, salt and horticulture, factors that also deserve special attention. Thus, the awareness of the study field environmental stage demands studies from researchers and discernment from society, as a way of understanding the inter-relation between environment and men. Therefore, this work attempts at understanding and studying the dynamics of land use in the lower course of Piranhas-Assu river, through a multitemporal analysis of present and past, accomplishing future projections through simulation models. The work is divided in stages that include the research, analysis, interpretation of results, and the generation of simulation models, to analyze the landscape tendencies, making possible to identify indicators which cause such changes in the lower course of the river. From Geographical Database, the necessary exploratory analyses were accomplished to the following items: land use evolution, natural and environmental vulnerability, multiple geodiversity indexes, and preparation of the data to be used in the simulation model. Later, the construction of the landscape simulation model was conducted. Sequentially, simulations of future sceneries were accomplished through the execution of the model in a specific software environment. Last, the analyses of landscape tendencies in the study field were carried out. The lower course of Piranhas-Assu River didn't show any intense dynamics in landscape changing, once in the period taken into account (from 1988 to 2004) class stability proved to be superior to its transformations. Activities related to agriculture and livestock are the ones that influence, mostly, the landscape dynamics. The production of sea shrimp and petroleum also infers in the landscape, although in smaller proportion. INCRA s public policies excessively determined the dynamics of the landscape in the lower course of Piranhas-Assu River, RN. In respect to its natural vulnerability, the lower course of Piranhas-Assu River, RN, features more vulnerable than stable areas. The landscape simulation, in the first taken period (2004-2009), indicated considerable increases and decreases of antropic activities, if compared to its sequent periods (2009-2014, 2014-2019 and 2019-2024). The simulation, in a wider analysis, showed that the determining factors for the space mobility of antropic activities, in the focused area, are related to the pre-existence of communities with agricultural capability and to the existence of access routes and drainage. Considering the area that features fixed and mobile dunes, located in Porto do Mangue district, we recommend its conversion into a conservation area

Dinâmica do uso e ocupação do solo no litoral de Macau-RN no período de 1978 a 2008

This study was developed in the northern coast of the city of Macau, a total area of 88,52 km², located in the State of Rio Grande do Norte. It presents relatively plain surface, with interlaced of streams and gamboas, characterized by contributions of oceanic water, flooding areas of swamps. Altogether, the climatic and topographical conditions provide an ideal environment for the development of saline activity. Inserted in the geologic context of the Potiguar Basin, the region presents favorable conditions for the production of hydro-carbons. It still presents natural conditions for shrimp breeding and artisanal fishing. This work analyzes the transformations occurred in the land use, using air photographs of 1978, Landsat 5 ETM Images of 1988, 1998 and 2008. A secular analyzes was carried through the dynamics of the use of the territory and the transformations occurred in the landscape due to the increment of the productive activities. In the survey of the data for study of the area, it was verified that little alteration occurred in the 30 years. The saline activity that was present since the year of 1978 having an increase of about 5% in thirty years; the shrimp breeding activity that had its presence in the decade of 1990, presented a high growth in the land use, therefore in 1998 it presented 0.45% and currently it presents 6.59%. In the field it was observed that great areas used previously for the saline activity, today it is prepared for shrimp breeding and that the areas of petroleum exploration occupy salt mines, beaches and trays. In 1988 it presented a percentage of 0, 07% and currently it occupies 0.46%, having grown 50% in the last 10 years. Although the variation of the occupation of the area has been little expressive, shrimp breeding showed a growth of 1,200% in only 10 years. In regards to petroleum activity, there wasn t any demonstration of an increasing impact in the land use in the area of study in 26 years of exploration
